These days you can see athletes endorsing oxygenated water. National shuttler Lee Chong Wei is one of them. There is very little oxygen in water in the first place and even if it is seven or ten times the oxygen content of normal water as has been claimed, this is negligible. Humans breathe in oxygen via the lungs, not via the gastrointestinal tract, for we do not have gills like fish. Oxygen is unlikely to bind with water, and even if it did, how can it reach the cells if taken via the gastrointestinal tract. Why didn’t the person who invented the technology of binding oxygen to water win any scientific awards if there was such a technology? And if the oxygen is compressed into the bottle, surely it will dissipate when you open the cap.
Moreover, super-oxygen water usually costs three times the price of normal bottled water. We humans were not designed to absorb oxygen via the stomach. That’s basic science. Some things that Mother Nature created can’t be changed. If anything is free, it is oxygen. Just take a few deeper breaths and there you instantly have more oxygen in your blood than drinking a bottle of super-oxygenated water.
It is the red blood cells that deliver oxygen to the cells and organs. Oxygen deprivation to the cells is due to many reasons such as atherosclerosis or lead poisoning whereby the red blood cells cannot bind oxygen well.
So please don't buy the expensive water as it won't enhance your exercise performance.
